Description
2357930 PORTABLE TELEPHONE DEVICE The present invention relates to a
portable telephone device, and particularly to a portable telephone device equipped with a speaking state display means in order to display a speaking state.
A conventional portable telephone device was not equipped with means which informs the surroundings unintentionally that a user is talking over the telephone. In case that the user wanted to inform the surroundings unintentionally that he was talking over the telephone, he has detached an antenna originally provided for the portable telephone device and exchanged it for an antenna of which a leading end blinks on and off.
It has been said that to use a portable telephone at a location where many persons collect, for example, in a train is against manners. However, in circles such as an association of like-minded persons, to speak on the portable telephone is permitted in case of necessity; and there is also manners in which the surrounding people who are talking are silent in consideration of a person who has started making a telephone call. In this case, it is convenient to have the surrounding people be silent by exhibiting that the user is taking over the telephone by some methods and having them be conscious of it.
Further, whenthe user receives a soundless callbyvibrator at night, in case that he starts speaking suddenly, the surrounding people frequently look at him out of curiosity. Particularly, under condition where a small-sized portable telephone devLce hides itself in the palm of a hand or hair, in order to prevent him from seeming suspicious to them, there are some cases that he would like to show speaking on the portable telephone devLce to the surrounding people.
Under the above condition, a means which informs tie surroundings unintentionally that the user is talking over the telephone is desired. As one method for resolution, there is a conventional method that an antenna is privately exchanged to lighten the leading end of the antenna. However, there were some cases that this method was not preferable for the user from viewpoints of cost, working and antenna sensitivity, and also from a view point that many antennas on the market are types in which blinking on/off is performed with high brightness and at a high speed.
As the operation during speaking on the telephone tiat the surrounding people would like to be able to conf irm. as described above, there is an operation of memo recording that memo-records the speaking contents. However, we are anxious in case that it cannot be conf irmed from the outside that the memo recording function is normally operating even if a memo recording button is pushed on. The portable telephone device requires a new means that confirms the operation state during speaking on the telephone from the outside.
2 A first object of the invention is to provide a portable telephone device provided with a means which can inform the surroundings unintentionally that a user is talking over the telephone, which is a means other than a method that the antenna 5 is privately exchanged to lighten a leading end of the antenna.
Further, a second object of the invention is to provide, in a portable telephone device having a function of memo-recording speaking contents during speaking on the telephone, a portable telephone device provided with a means that visually confirms that the memo-recording function is operating.
According to the f irst aspect of the invention, a speaking state display means that goes on and off during speaking on a telephone is provided for a body case of a portable telephone device, and the speaking state display means is turned on and off by a control means at regular intervals when the portable telephone device enters on the speaking state. Further, according to the second aspect of the invention, a speaking state display means that goes on and off during speaking is provided on a back surface of a body case of a portable telephone device and at a position where the speaking state display means cannot be covered with a hand when a user holds the portable telephone device; and the speaking state display means is turned on and off by a control means at regular intervals when the portable telephone device enters on the speaking state.
By these constitutions, the surroundings can be informed unintentionally that a user is talking during speaking over the telephone.
According to the third aspect of the invention, a memo recording switch that starts a function of memo-recording speaking contents is provided for a body case of a portable telephone device, and the memo recording switch is used as a switch with a light emitting means that goes on and of f when the memo recording function is started.
By this constitution, a state during memo-recording operation can be conf irmed from the outside by the light emitting means that goes on and off when the memo-recording operatiDn is started.
According to the fourth aspect of the invention, one switch with a light emitting means is used both as a speaking state display means that goes on and off in a first color during speaking and a memo recording switch that goes on and off n a second color when a memo recording operation is started.
By this constitution, only by providing one switch with the light emitting means on a back surface of the body case, it can go on and off in the first color during speaking and go on and of f in the second color during the memo recording operati Dn. According to the f if th aspect of the invention, when the portaDle telephone device enters on the speaking state, the speaking state display means is turned on and off with brightness that a per son near the portable telephone device can identify while the brightness is being gently increased at regular intervals Dr gently decreased, whereby the speaking state display means is turned on and off just like a firefly.
By this constitution, the surroundings can be informed unintentionally that the user is talking over the telephone in an going on/of f mode that gives the settled feeling to a viewer, that is, in a mode in which light and darkness are slowly repeated with a brightness that only a person near the portable telephone can confirm, which is different from the going on/off mode in which going on and off are switched with high brIghtness and at a high speed like the conventional antenna of which the leading end is lightened.
A particular embodiment in accordance with this invention will now be described with reference to the accompanying drawings; in which:- Fig - 1A is an exterior perspective view in which an operational surf ace of a portable telephone devIce according to a mode f or carrying out the invention is shown upward; Fig. 1B is an exterior perspective view in which a back surface of the portable telephone device according to the mode for carrying out the invention is shown upward;

Fig. 1A is an exterior perspective view in which an operational surface of a portable telephone device according to a mode for carrying out the invention is shown upward. In a body case 1, there are arranged a receiver 2, a transmitter 3, a key operational portion 4, and a display portion 5.
Particularly, in the key operational portion 4, there is provided a memo recording button 6 functioning as a memo recording switch that starts recording the speaking contents by being pushed on during speaking on the telephone.
Fig. 1B is an exterior perspective view in which a back surface of the portable telephone device according to the mDde f or carrying out the invention is shown upward, in which a speaking state display portion 7 that goes on and off when the portable telephone enters on the speaking state is provided.
Fig. 2 is a function block diagram of the portable teleph)ne 6 device according to the mode for carrying out the invention. In Fig. 2, a radio wave received by an antenna 8 is received by a receiving portion (not shown) of a radio communication portion 9, and the reception data is transmitted to a control portion
10. The control portion 10 displays the reception data such as a telephone number that has been received in a display portion 11 such as a liquid crystal display. Further, the control portion 10 converts the reception data into audio data and speech-outputs the converted data through a speaker 13 of a receiver portion.
Further, a transmitter portion (mike) 14 receives the voice of a user, transmits the audio data to the control portion 10, and audio-transmits the audio data through a transmitter portion (not shown) of the radio communication portion 9 and the antenna 8 to a person on the other end of the line. The control section 10 causes a memory 16 to record the audio data such as the speaking contents during speaking, or reads out the data recorded in the memory. A key operational portion 12 such as a ten key inputs signals to the control section 10 by key operation or causes the memory 16 to record private data in an electronic telephone directory through the control section 10. Further, a speaking state display 15 provided separately from the display portion 11, when the radio communication portion 9 starts the radio communication, is turned on and of f by the control of the control portion 10 at regular intervals. Since the speaking state display 15 is provided on the back surface of the body case 1 and a position where it is not covered with a hand when the portable telephone 7 - is held as shown in Fig. 1B, it is possible to inf orm the surroundings that a user is talking during speaking on the portable telephone.
When the portable telephone enters on the speaking state, the control portion 10 turns on and of f the speaking state display 15 by gently increasing and decreasing the brightness at tie regular intervals. In order to turn on and off the speaking state display by gently increasing and decreasing the brightness, a square wave from the control portion 10 (control signal Ln Fig. 3) is converted by a RC filter into a gentle control sig,'lal (af ter passing the RC f ilter in Fig - 3) In Fig. 3, Rl = 1001-p, R2 = 120Q, and Cl = 109F.
Such going on/off mode that the speaking state display goes on and off while the brightness is gently increasing and decreasing makes a soft and quiet impression on a viewer as if a firefly glistens. Further, the brightness is previously set to a comparatively low degree with which a person near the portable telephone can identify the brightness, whereby the consuming electric power of a battery is suppressed low and hindrance is not given to a speaking time of the portable telephone. Asdescribed above, according to the invention, during speaking on the portable telephone, the user can inform the surroundings unintentionally that he is talking.
Further, according to this function of displaying the speaking state, when the person on the other end of the line becomes silent and there is not any sound, a speaker can visually confirm that he has cut the telephone or that he has been speak-ing yet by looking at the speaking state display portion 7.
Fig. 4 is a sectional view showing a structure of the memo recording button 6. In a sectional view of Fig. 4A, two contact patterns 19 are spaced and printed on a print substrate 18. In the center of the two contact patterns 19, a LED 20 is arranged, and a key button 22 is shown. By a furcate leading end portion of the key button that has a conductive film 21, the contact pattern 19 is pushed on. When the key button 22 is pushed on from the upside, a connecting portion with a skirt portion 23 is transformed and descends downward, so that the conductive film 21 comes into contact with the contact pattern 19 of the print substrate 18. Then, the LED 20 is turned on and off by a going onloff circuit (not circuit), and the key button 22 is illuminated.
Fig. 4B is a plan view showing arrangements of the contact patterns 19 of the print substrate 18, the LED 20 and a rib 24 that surrounds them and reflects the light of the LED 20. Fig. 4C is a sectional view taken along a line shown by an arrow A, showing a state where the key button 22 rises by the force of the skirt portion 23 after the key button has been pushed on, and returns to the position where it comes into contact with a case 25, and the LED 20 that has started going on and off once is continually illuminating the key button 22.
By pushing on the key button 22, the control portion 10 starts the memo recording operation, records the speaking contents in the memory 16, and simultaneously, turns on and off - - -------- the LED 2 0. Hereby, the speaker can confirm the memo record Lng operation by the going on/off of the LED 20 during speakinj. The going on/off mode is shown in Fig. 3.
Fig. 5 is a constitutional block diagram in a second mode for carrying out the invention, in which a switch 26 with a light emitting means is used as both the speaking state disp.,Lay portion 7 and the memo recording button 6 that have been described in the f irst mode. To say concretely, the switch with the light emitting means 26 used as the memo recording button 6 is arranged at a position of the speaking state display portion 7 on the back surface of the body case in the first mode shown in Fi9. 1B.
Fig. 6 is a flowchart showing the speaking state display operation during speaking and an operation when the memo recording is perf ormed on the way. First, when the power is switched c n, the portable telephone device enters on a reception waiting state (step 1). In case that there is a call, the portable telephcne rings (step 2). When the user pushes on a speaking button (step 3), radio communication is started (step 4).
The control portion 10, when the radio communication is started, turns on and off the speaking state display 15 in a first light emitting color, for example, blue (step 5). 'En case that the speaking is completed intactly, the procedure returns to the reception waiting state (step 6). When the memo recording button 6 which is a memo recording switch is pushed on duriig speaking (step 7), the LED 20 of the memo recording button goes on and off in a second light emitting color, for example, red (step 8). Thereafter, when the memo recording is finished since the predetermined time has elapsed, or when the memo recording button 6 is again pushed on in a sense of the memo recording finish and the memo recording is finished (step 9), the LED 20 goes on and of f as the speaking state display 15 in blue of the first light emitting color (step 10). Thereafter, when speaking is finished, the procedure returns to the reception waiting state (step 11).
By performing the above operations, it is possible to inform the surroundings unintentionally that a user is talking during speaking on the portable telephone through the going on/of f state of the speaking state display 15 provided on the back surf ace of the body case. Further, the speaking state display functions also as the memo recording switch, whereby it is used as the means f or displaying the memo recording operation during speaking, so that the user can confirm the memo recording operation during speaking.
As described in the first mode for carrying out the invention, the speaking state display portion goes on and off, for example, in blue during speaking on the portable telephone, whereby it is possible to inf orm the surroundings unintentionally that the user is speaking on the telephone. Further, as described in the second mode f or carrying out the invention, when the speaking button is pushed on during speaking, the speaking state display portion goes on and off in red, whereby it is known that the portable telephone is during the operation of the speaking me no. Since the operational surface of the telephone comes into tight contact with his surface particularly during speaking, he can'lot look at the liquid crystal display portion. However, since he know that the speaking state display portion goes on and off, for example, in blue during speaking and that it goes on and of f in red during the memo recording operation, he can confirm that the portable telephone is in the speaking mode or the speak.Lng memo mode by reflecting himself who is speaking on the telephone in a mirror or a glass of a show window on a street to see the going on/off state by necessity. Though it is inconvenient for the user to see the going on/of f state indirectly, since he could not conf irm the going on/of f state conventionally during speakii 9,' a newest effect can be obtained.
Further, as shown in Fig. 1B,, if an illustration similar to that of a person who lowers his head together with characters that I am sorry to be such a nuisance to you due to noisy is made on one side of the speaking state display portion 7, eien when the user is compelled to speak on the portable telephcne in a train, he can express a feeling of apology with the going on/off of the speaking state display portion 7 in relation to the surrounding people. Therefore, there is such an effect on use that a mental load on the speaker at the time of speaking there can be reduced.
As described above, according to the first aspect of the invention, the speaking state display means that goes on and off during speaking is provided for the body case of the portable telephone device; and the speaking state display means is turned on and off by the control means at regular intervals when the portable telephone device enters on the speaking state.
Hereby, there is an ef f ect that the surroundings can be informed unintentionally during speaking that the user is talking over the telephone.
According to the second aspect of the invention, the speaking state display means that goes on and of f during speaking is provided on the back surface of the body case of the portable telephone device and at the position where the speaking state display means cannot be covered with a hand when a user holds the portable telephone device; and the speaking state display means is turned on and of f by the control means at regular intervals when the portable telephone device enters on the speaking state.
Hereby, there is an ef f ect that the surroundings can be informed unintentionally during speaking that the user is talking over the telephone.
Further, according to the third aspect of the invention, the memo recording switch that starts the function of memo-recording the speaking contents is provided for the body case of the portable telephone device, and the memo recording switch is used as the switch with the light emitting means that goes on and off when the memo recording function is started.
Hereby, there is an ef f ect that the state during the memo-recording operation can be confirmed from the outside by the light emitting 13 means that goes on and off when the memo-recording operatiDn is started.
Further, according to the fourth aspect of the inventi:)n, one switch with the light emitting means is used both as the speaking state display means that goes on and of f in the f irst color during speaking and the memo recording switch that goes on and of f in the second color when the memo recording operation is started. Hereby, there is an effect that only by providing one switch with the light emitting means on the back surface of the body case, it can go on and off in the first color during speaking and go on and off in the second color during the memo recording operation.
According to the fifth aspect of the invention, whEn the portable telephone device enters on the speaking state, the speaking state display means is turned on and of f with brightnIE ss that a person near the portable telephone device can identify while the brightness is being gently increased at regular interva ls or gently decreased, whereby the speaking state display means is turned on and off just like a firefly. Hereby, there is an effect that the surroundings can be informed unintentionally that a user is talking over the telephone in a mode that gives the settled feeling to a viewer, that is, in a mode in which light and darkness are slowly repeated with such a brightness that only a person near the portable telephone can confirm, which is dif f erent from the mode in which going on and off are switched with high brightness and at a high speed like the conventional - 14 antenna of which the leading end is lightened
